Bitmain Antminer T19 Hydro Overview

The Bitmain Antminer T19 Hydro is a liquid-cooled ASIC miner designed for the
SHA-256 algorithm. It can mine Bitcoin, Bitcoin Cash and other compatible
proof-of-work cryptocurrencies through a suitable mining pool.

Unlike air-cooled miners, the T19 Hydro does not rely on conventional high-speed
cooling fans. Heat is transferred through a controlled liquid-cooling circuit,
making the miner suitable for professionally designed mining farms and compatible
hydro containers.

An experienced Antminer T19 Hydro seller should clearly state
the exact hashrate version, equipment condition, tested power draw, cooling
compatibility and warranty terms.

Antminer T19 Hydro Technical Specifications

official Bitmain T19 Hydro specifications

before purchasing or planning an installation.

Important Antminer T19 Hydro Features

Up to 138.5 TH/s SHA-256 Performance

The highest official T19 Hydro configuration delivers 138.5 TH/s with a manufacturer
tolerance of approximately ±3%. Pool-side performance can vary with network latency,
firmware, coolant temperature and miner condition.

Liquid-Cooled Thermal Management

The hydro system transfers heat into a circulating coolant loop rather than relying
on conventional miner fans. This allows the machine to operate in professionally
engineered high-density mining environments.

Integrated APW11 Power Supply

The APW11 power supply is integrated into the miner. The unit requires a compatible
high-voltage electrical system and should not be connected to an ordinary household
outlet.

Wired Ethernet Connectivity

The T19 Hydro uses RJ45 Ethernet rather than Wi-Fi. A stable wired connection helps
maintain pool uptime and reduce rejected shares.

Purpose-Built Mining-Farm Deployment

The miner is intended for industrial or professionally managed installations.
Bitmain’s setup guidance specifies operation with the ANTSPACE HK3 hydro system.

How to Choose an Antminer T19 Hydro Seller

A reliable Antminer T19 Hydro seller should provide evidence that
the exact miner has been tested under appropriate cooling and electrical conditions.

Verify the Exact Model

Request photographs of the model label and serial number. Confirm that the unit is
genuinely a T19 Hydro and not an S19 Hydro, S19 Pro Hydro or incorrectly labelled
145 TH/s model.

Request Current Test Results

Ask for screenshots showing pool-side hashrate, detected hashboards, chip status,
coolant temperature, power draw and hardware errors.

Confirm Cooling Compatibility

The seller should explain which cooling container, coolant system, hoses, connectors
and heat-rejection equipment are required. The miner should not be powered without
correct coolant circulation.

Review Warranty Terms

Confirm which components are covered, the warranty period, return-shipping
responsibility and the procedure for damaged-on-arrival claims.

Verify Shipping Protection

Hydro miners should be drained, protected from contamination and packed securely
before transport. Ask how the coolant ports and internal system are prepared for shipping.

Antminer T19 Hydro Cooling Requirements

The T19 Hydro cannot operate safely as a standalone air-cooled machine. It requires
a compatible liquid-cooling loop capable of maintaining stable coolant flow,
pressure and temperature.

• Maintain approximately 8 L/min coolant flow per miner.
• Keep water pressure at or below 3.5 bar.
• Use the coolant type recommended for the cooling system.
• Remove air from the loop before powering the miner.
• Check all connectors and hoses for leaks.
• Monitor coolant inlet and outlet temperatures.
• Provide sufficient external heat rejection.
• Do not power the miner without coolant circulation.

Bitmain states that the firmware can stop mining if the PCB reaches approximately
80°C or if water temperature moves outside the supported range. Cooling alarms should
never be ignored.

Antminer T19 Hydro Electrical Requirements

The miner requires approximately 5,194W under rated conditions. Continuous operation
therefore uses about 124.66 kWh per day and approximately
3,739.68 kWh over 30 days.

Bitmain specifies an AC input range of 342–418V and notes that incorrect voltage can
damage the equipment. The electrical supply, disconnect device, grounding, surge
protection and cable sizing must be designed for the installation.

Bitmain also requires an external surge-protection device and a disconnecting system
capable of disconnecting the relevant power conductors simultaneously.

Electrical installation should be designed, completed and inspected by qualified
professionals familiar with high-power industrial mining equipment.

Used and Refurbished Antminer T19 Hydro Units

Many available units may be used or refurbished. The seller should disclose the
machine’s operating history, repair history and cooling-system condition.

Used Units

Used hydro miners may show corrosion, coolant residue, connector wear, scale buildup
or previous leak damage. Internal passages should be inspected and cleaned correctly.

Refurbished Units

Refurbished units may include repaired hashboards, replaced control boards, serviced
power supplies or renewed coolant fittings. Ask who completed the repairs and how the
machine was stability-tested afterward.

New Old Stock

A miner described as new should include matching packaging and serial details, along
with evidence that it has not been deployed in a commercial mining environment.

Antminer T19 Hydro Profitability Considerations

Purchasing from an experienced Antminer T19 Hydro seller does not
guarantee profitable mining. Financial performance changes with market and network
conditions.

• Bitcoin market price
• SHA-256 network difficulty
• Block reward and transaction fees
• Electricity cost per kilowatt-hour
• Mining-pool fees
• Coolant-pump and cooling-system electricity
• Heat-rejection and facility expenses
• Miner uptime and rejected shares
• Maintenance and repair costs
• Shipping, taxes and customs duties

Include the electricity consumed by pumps, dry coolers, container systems and other
supporting equipment when calculating total operating cost.

Antminer T19 Hydro Buying Checklist

• Confirm the exact model, version and rated hashrate.
• Verify that the unit is a T19 Hydro rather than an S19 Hydro.
• Request current serial-number photographs.
• Ask for a recent pool-side hashrate test.
• Verify hashboard, chip and power-supply condition.
• Inspect coolant ports for corrosion or leakage.
• Confirm the required coolant flow and pressure.
• Verify compatibility with the planned cooling system.
• Confirm the 342–418V electrical requirement.
• Review warranty and return terms in writing.
• Calculate freight, insurance, duties and taxes.
• Use a secure and traceable payment method.

Antminer T19 Hydro Seller FAQs

What is the official T19 Hydro hashrate?

Bitmain officially lists 119, 125.5, 132 and 138.5 TH/s versions. The highest
official T19 Hydro configuration is 138.5 TH/s.

Is there an official 145 TH/s T19 Hydro?

Bitmain lists 145 TH/s under the S19 Hydro family, not the T19 Hydro family.
A seller advertising a 145 TH/s T19 Hydro should provide model-label and test evidence.

How much power does the 138.5 TH/s model consume?

The official reference power is approximately 5,194W with a tolerance of ±5%.

What is the efficiency of the T19 Hydro?

Bitmain rates the official T19 Hydro versions at approximately 37.5 J/TH ±5%.

Does the miner include its own cooling system?

No. The miner requires a compatible external hydro-cooling system, pumps,
heat rejection and properly connected coolant lines.

Can the T19 Hydro run in a normal home?

It is generally unsuitable for a normal household because it requires high-voltage
power, professional liquid cooling and more than 5kW of continuous electricity.

What coolant flow does it require?

Bitmain specifies approximately 8 L/min with a tolerance of ±10%.
